The device (1) activates a lifting mechanism (2) with ropes (21, 22, 23, 24) of a suspended bed (3), with the same ropes (21, 22, 23, 24) deflected below the supporting frame (20) of the bed (3) and fixed to a common draw hook (26), moved by the device (1), in which are provided: a pulley (4), rotatable horizontally under the supporting frame (20); a cogwheel (40), integral with the pulley (4); a gas spring (5), with a rack (50) engaged with said cogwheel (40) to operate it in rotation; a flexible cable (6), secured with one end to the pulley (4) and partially wound on the latter, and secured with the remaining end to the draw hook (26). The lifting of the bed (3) takes place with the rotation of the pulley (4) pushed by the gas spring (5), whereby the flexible cable (6) pulls the draw hook (26) causing the dragging of the ropes (21, 22, 23, 24); in the lowering, vice versa, the ropes (21, 22, 23, 24) drag in the opposite direction the draw hook (26) which, in turn, pulls the flexible cable (6), thus rotating the pulley (4) in the opposite direction and reloading the gas spring (5).
